Sound sensor distance represents a critical technological capability for measuring spatial relationships using acoustic wave propagation. Ultrasonic distance sensors can detect objects from 2cm to 400cm with remarkable precision, leveraging sound wave reflection to calculate spatial positioning across various environmental conditions. These sensors provide non-contact measurement solutions critical in robotics, automation, security systems, and industrial applications.
